IPv6: 10 Things You Didn’t Know About Internet Protocols

The Internet Society, an international nonprofit organization that advises on Web standards, policy and education, has selected June 6, 2012, as the World IPv6 launch day. This date will mark the beginning of a new phase in the life of the Internet, when IPv6 begins to become a normal part of the Internet experience for everyone—taking over from IPv4. Last year, the Internet Society declared June 8, 2011, as World IPv6 Day to give enterprises and Internet service providers (ISPs) a chance to “stress test” the next-generation Internet protocol to see what works, what breaks and what they need to do to seamlessly migrate their networks to IPv6.

At some point, the entire Internet infrastructure has to move to using the newer address space, since the differences in the protocols mean that computers with IPv4 addresses cannot communicate with machines with IPv6 addresses. The Internet Society says that time is now. eWEEK takes a look at some of the key differences between IPv6 and IPv4. It also identifies some information you may not know about IPv6.
